I’m told those born in this year are clever, ambitious, creative, hard-working, fastidious, charming and sociable, but can be a bit stingy when it comes to sharing their wealth or possessions. For those looking for romance, Rats are compatible with Dragons, Monkeys and Oxen, but should avoid Horses at all costs! China - On the 8th August, the Chinese capital Beijing will host the Games of the XXIX Olympiad – One World One Dream. There are 28 sports on the program with over 10,000 athletes from around the globe competing. Happy Blue Year - Leading colour supplier Pantone, have declared Blue Iris as their signature colour. The blue is a radiant, calming hue, dark, but not dark enough to be in the realm of navy. PANTONE Blue Iris 18-3943 Tokyo - Japan will host the summit of the Group of Eight nations. Japan will assume the G8 Presidency for the fifth time and will hold the Summit at Toyo Lake in Hokkaido. It has been suggested that our own Natchan Rera (Hull 064) may play an active role during this period. XXIII World Youth Day - Sydney will host the largest youth event in the world in July. Organized by the Catholic Church, it will be the first visit of His Holiness Pope Benedict XVI to Australia The United Nations Headquarters - has declared that it will be the International Year of the Potato. It will highlight agriculture in general, addressing issues of global concern, including hunger, poverty and threats to the environment Year of the Frog - AArk - Amphibian Ark will lead zoos, botanical gardens and aquariums in a globally coordinated campaign for public awareness and understanding of the amphibian extinction crisis which represents the greatest species conservation challenge in the history of humanity. That is just some of what 2008 is going to be all about. So, wherever you are this New Year have a happy and successful one. EDITOR- Kim Clifford I love a New Year a time for family, for reunions, for taking stock, for looking back and looking forward. 2007 was a good year for Incat but, you know what, 2008 will be even better. In 2008 we’re going to keep up the momentum and keep the shipyard moving forward. If 2007 is remembered as a year of significant achievement in the launch of the first 112m, then 2008 will be a year of continued product improvement and technology advancements. As 2008 is a leap year, it will be made up of 366 days. There’ll be 1440 minutes in each of these days, or 86,400 seconds. Which aren’t many really, especially if you have a boat to deliver by the second week of April! The year, in total, will provide you with a wondrous 8784 hours, and if you’re one of the lucky ones who gets eight hours sleep, that figure will be reduced by 2928. This leaves a grand total of 5856 productive hours. How many will be spent at Incat? – probably not as many as our boss would like!

While it is Fjord Line which is taking over Master Ferries, the shareholders in the latter continues with its ownership of the company. It is now the intention that the new-look Fjord Line will be publicly quoted on the stock exchange in 2009. Ingvald Fardal, who has extensive experience from similar operations and other transportation companies, started as managing director in Fjord Lines in October 2007. He carries on as managing director in the new company with Øystein Glad from Master Ferries as director for the route between Kristiansand and Hanstholm. Svein Ege and Gert Balling from Fjord Line continues as respectively finance director and director for the operation in Denmark. Master Ferries brings the Master Cat to Fjord Lines, continuing its summer operation between Kristiansand and Hanstholm. Being among the fastest ferries in the world , the Master Cat, now named Fjord Cat, only takes two hours to do the crossing, which is much faster than the competitor’s conventional ferry. The High Speed Vessel (HSV) 2 Swift (Hull 061) started 2008 by heading for the west coast of Africa to join the US Navy’s Global Fleet Station (GFS), Africa Partnership Station (APS) initiative. Teamed with the dock landing ship USS Fort McHenry (LSD 43) the Swift embarked Commander Task Group 60.4, from Naples, Italy, already on station, to take part in the first GFS APS initiative. “In a nutshell, we’ll be trying to develop stronger maritime security ties,” said Commander Charles Rock, commanding officer of Swift’s Ingleside, Texas crew. “We’re loaded with humanitarian assistance, food and aid donated by non-governmental organisations, so we’ll be delivering a lot of good will.” APS is a US Naval Forces Europe-led initiative, executed by a multi-national staff aboard the Fort McHenry and Swift. Training teams from various US and European military commands, as well as governmental and non-governmental organizations work together to enhance cooperative partnerships with regional maritime services in West and Central Africa and the Gulf during the deployment. The Swift joined the Fort McHenry in the Gulf of Guinea and on 28th January sailed into Lome, as the first US Navy ship to visit Togo in 15 years. “We’re a unique ship, different than any other I’ve served on. Because of that, we can get into ports that other ships can’t. I just think the opportunity to visit a country like Togo is extremely unique,” Cmdr. Rock said. Prior to the merger, Fjord Line held a market share of 3% of the total passenger traffic between Norway and foreign countries while Master Ferries held 4%.

Justin Merrigan Jaume III 10 Incat THE Magazine Issue 34 This year marks the tenth anniversary of Spanish ferry operator Baleària and what better way to celebrate than positioned as the leader in marine transport in terms of traffic to and from the Balearic Islands and interislands. Not only that, but following the acquisition of Buquebus España the company strives ahead in 2008 by fully expanding into the competitive Straits of Gibraltar market. Driven by a group of executives and captains from the former shipping company Flebasa, Eurolinies Maritimes was launched in July 1998 under the brand Baleària. Adolfo Utor Martinez was nominated president of the new company and under his guiding hand the company outlined an extensive action and modernisation plan for its fleet, with a very clear focus on the latest generation of high speed ships then available. Initially the company operated the Denia-Ibiza-Palma, Ibiza-Formentera, Ibiza-Palma and Denia-Ibiza routes, but expansion soon came and in June 2000 the Valencia-Palma link was added to the network. Baleària’s pledge to provide its customers with maximum comfort in the shortest possible time started in July 2001, incorporating the new fast ferry Federico Garcia Lorca into its fleet. This ship represented a revolution for the company, linking the islands to mainland Spain in just two hours. This revolution has since been consolidated thanks to important investments in the most innovative and competitive naval technology and effective strategies, which have permitted the fleet to continually expand and progressively open new lines. The fundamental goal of Baleària is to act as a bridge between In July 2002 another route was introduced, that between the Balearic Islands and mainland Spain. This represents a Alcudia and Mahon and three months later the Rodriquez- commitment with the islands which has resulted in the opening built high-speed ferry Ramon Llull was launched. But even of new lines and introduction of new ships until attaining its greater expansion beckoned on the western horizon. current position as the only shipping company which joins all four Balearic Islands with mainland Spain, as well as providing daily links between them. As such, their routes meet the needs of both tourist and island residents alike, the services seen as a comfortable, reliable and competitive means of transport, both for travelling between islands and for trips to mainland Spain. Locally, it is easy to see Baleària’s clientele values the frequency and punctuality of the services - a timetable which adapts to their needs and good quality service at the best price. Each year Baleària transports over 2 million passengers, more than half those travelling by sea to the Balearics travelling on a Baleària vessel. Taking Baleària to the Straits At the beginning of 2003, Baleària created the Nautas Al-Maghreb company for a new route between the Moroccan city of Tangier and Algeciras, located in the extreme south of the Iberian Peninsula, and two years later the company took delivery of its first Incat craft, the 78 metre Incat 033. In collaboration with a public television program broadcast by the Catalonian TV3 the craft was christened Jaume I by her new owners. Viewers of the program El Favorit were asked to choose their favourite historical figure from Catalonia and the person chosen was Fast Ferries at Barcelona Ramon Lllull and Jaume I (Hull 033) Incat THE Magazine Issue 34 11 the XIII Century king responsible for the significant expansion their arrival has enabled Baleària to considerably strengthen its of Catalonia, including the conquering of the Arabs controlling profile.

The entrance of Baleària into this market is the result of a or Jaume series. All three are now operating the Straits of joint venture with CMA-CGM, one of the main maritime Gibraltar routes, where service is provided from Algeciras to operators worldwide. Ceuta (Spanish city located in North Africa) as well as Tangier. In what is known as “Operación Paso de Estrecho” (Operation Strait Crossing), when hundreds of thousands of Moroccan citizens residing in Europe travel to their country of origin, the Incat “serie Jaume” vessels operate non-stop 24 hours a day, with short breaks for maintenance operations. There are two crews with rotating shifts commanding each ferry. Hungry for Expansion! Baleària’s position in the Straits of Gibraltar was further strengthened in 2007 with the purchase of rival operator Buquebus España and as a result, traffic forecasts predict that in 2008 the company will provide services to 4 million customers. Spain’s council of ministers approved the takeover on 14 September, after Spain’s competition authority, the Tribunal en Defensa de la Competencia had given the green light to Balearia’s aspirations. With the purchase of Buquebus came Baleària’s fourth Incat ferry, the 74 metre Patricia Olivia. While significant growth was taking place in the high speed business, Baleària has also been careful to make investment across its fleet of conventional ferries. In 2003 the company bought the shipping interests of the Matutes group which previously traded as Umafisa. One happy consequence of this move was the reuniting of the Jaume I with the Isla de Botafoc – both vessels having partnered each other for Stena Line on the Irish Sea as Stena Sea Lynx II and Stena Cambria respectively! More recently Baleària increased its services through the addition of the Ro-Pax ferries Borja and Borja Dos on the routes to Palma de Mallorca from Barcelona and Valencia. These are the highest capacity vessels operating routes to the Islands and 12 Incat THE Magazine Issue 34 With such investment and vision Baleària is well placed in the European ferry industry. And while it can accredit many factors for its success, the company is quick to point out that this growth was made possible thanks to the effort of its staff of approximately 1,000 employees, a team committed to the company and its mission. The Borja operating between Barcelona and Palma Jaume 1 leaving Barcelona Isla de Botafoc Baleària is proud of its commitment to society, and especially to the cultural and environmental future. The fight against climate change, a global challenge, is one of Baleària’s objectives. This objective is met through compliance will all environmental regulations and guidelines, even before they come into force; specific actions taken in collaboration with universities, government bodies and ecologist groups and a R&D&I program for the construction of new vessels prioritizing the optimization of energy resources. On board Borja Quality Compliance Providing a quality service which satisfies the needs and expectations of customers is the key to Baleària’s success. The ISO 9001:2000 certification includes analysis tools, such as the European form for consumer complaints, which permit the company to track customers´ satisfaction and to anticipate future needs. Baleària also shows a commitment to the environment. The company is aware of the need to preserve the physical balance of the Mediterranean Sea and their commitment to the environment goes beyond the requirements of international treaties. The company has its own quality standards regarding the collection and treatment of oil waste. Each year over 500 tonnes of such waste is collected from the fleet, treated and later recycled. Incat THE Magazine Issue 34 13 The HOLY GRAIL of High Speed Ferries! In Search of Speed, Efficiency and Passenger Comfort Speed and deadweight have traditionally been the subject of passionate discussion in the High Speed Craft (HSC) industry, but sea keeping is the new hot topic among operators and observers alike. The effect of size and hull separation on a catamaran’s sea keeping is significant; greater size and increased hull separation decreasing vessel motions and accelerations. However, it is often suggested that increased hull separation increases Metacentric Height (GM) and motions. Here, we dispel that myth for Wave Piercing Catamaran designs where GM increases but so do roll inertia, virtual roll inertia and roll damping leading to a reduction in motions at increased hull separation. The use of GM alone is only applicable to calculate roll motions for monohull type vessels and is not applicable to multi-hulls. It has been found that the Incat 112 metre Wave Piercing Catamaran (WPC) delivers significant improvements in sea keeping over smaller Incat vessels and this can be related to the increased hull separation (overall beam), increased length and vessel mass. Additionally the 112 metre WPC’s increase in tunnel clearance and arch shape provides significant improvements, making the vessel ideal for those longer and more exposed sea crossings. The 96 and 98 metre WPCs carry an impressive 500 tonne at 40 knots. The 112 metre WPC’s efficiency is uncontested amongst its competitors with its ability to carry 1000 tonnes deadweight (DWT) at 40 knots. Gary Davidson, Tim Roberts, July 2007 The selection of a High Speed Craft should not depend on perceived sea keeping benefits but on speed, efficiency, operating costs and actual passenger comfort. A speed and deadweight target for HSC has long been 40 knots with 1000 tonnes deadweight. Revolution Design/Incat set out to achieve this virtual Holy Grail for HSC and the current 112 metre WPC design is the result of over five years research and development. Today, a speed of 40 knots and 1000 tonnes DWT is possible depending on the hull and cabin arrangement. 14 Some areas of industry discussion wrongly suggest that catamarans are not conducive to good sea keeping. Comparisons have generally compared a 26% greater waterline length (LWL) and 14% greater beam vessel against the 96 metre WPC. Other comparisons have been published but with insufficient information on the catamaran vessel to understand why there is such a difference. Generally most of this discussion suggests that catamaran motions are similar to monohull and monohull type vessels in head seas, but are poor in beam seas. In service experience shows improvements in seasickness rates of the 96 and 98 metre WPCs over smaller vessels. This is a good result for the 112 metre WPC. Being a much longer, wider and heavier vessel, the sea keeping is similarly improved but with greater efficiency than any competitor competitor. Incat THE Magazine Issue 34 SPEED AND EFFICIENCY To increase the speed of a vessel the length to breadth (L/B) ratio must be increased to reduce the wave making resistance, Dubrovsky, (2001). For a monohull this means a very long length or the stability of the vessel will be compromised. The Pentamaran, Dudson, (2001) and the Austal Trimaran, Armstrong, (2003) have been designed to overcome this limitation by providing outriggers to a monohull to provide the necessary stability while reducing L/B to an appropriate figure. The L/B of each hull of the catamaran is restricted only by the size of the waterjet. On a catamaran, with its two waterjets per hull, it is easier to achieve a high L/B for each hull whereas the stabilised monohull must have three or four waterjets. An un-stabilised monohull would not be able to achieve the same L/B ratio unless it was very long. The disadvantage of length in this respect is that the vessel lightship weight could become unreasonable and the vessel may not be practical for some of the ports HSC use. In general a high speed catamaran has shorter length than an equivalent monohull or stabilised monohull. Equivalence here means similar speed and carrying capacity. For commercial operations in today’s economic climate the efficiency of the vessel is very important. It can be seen that at equivalent payload and power, the vessel that can go faster should be the most efficient. Catamarans and especially WPC designs have superior speed and efficiency. MOTIONS The predominant motions for most ships are generally pitch, heave and roll. 3 Pitch is a rotation around a transverse axis and results in the bow going up as the transom is going down and vice versa. Heave is the whole vessel going up or down evenly. Roll is the rotation around a longitudinal axis with the port side going down while the starboard goes up or vice versa. 2.5 2 1.5 A typical Response Amplitude Operator (RAO) is shown in figure 1 and it can be seen that the amplitude tends to peak at a certain encounter period. In beam seas the encounter period is equivalent to the wave period. In head seas the encounter period decreases as the vessel goes faster, since the vessel sees more waves the faster it goes. At zero vessel speed the encounter period would match the wave period but as the vessel gains speed the encounter period decreases. In following seas vessel speed increases the encounter period or less waves are seen. 1 0.5 0 0 5 10 15 20 25 30 35 Wave Period, secs 40 45 50 55 Figure 1, Typical RAO, pitching motions, no ride control 8 It can be seen from the RAO in figure 1 that the motion increases significantly at a certain wave period seen by a large peak. The wave period associated with the peak should be avoided in operation. A change of heading and/or speed can change that encounter period. The wave encounter period is more important than the wave height. A resonance is set up when the vessel natural period matches that of the encounter period. 7 6 5 4 3 2 1 0 50 100 150 200 Wave Length, m Figure 2, wave slope per metre amplitude 250 300 As waves get longer the wave slope reduces, this is intuitive, and a wave of 1m height at 40m length has to be steeper than a wave of the same height at 100 m length. Figure 2 plots the wave slope/ metre amplitude versus wave length. It can be seen clearly that a ship that is in resonance with a 50 m wave is meeting a wave much steeper than a vessel in resonance with a 100m wave. Incat THE Magazine Issue 34 15 ROLL It has been suggested that the sea keeping of a catamaran is reliant on its transverse GM. This is a measure of a vessel’s stability - the higher the value the greater the stability. In monohull theory it can also be used as a measure of vessel motions. Catamarans can have GM ranging from 20 - 40 metres depending on size whereas a monohull GM can be as low as 4 metres. Further, it has been suggested that catamarans have high accelerations in beam seas due to their short roll period when compared to the longer roll period of a monohull. Dubrosvsky, (2001) considers a well designed catamaran to have two to three times less roll amplitude than an equivalent monohull with equal accelerations. That is not the experience with WPCs; in fact it has always been felt that catamarans roll much less than a similar size monohull. Dubrosvsky, (2001) considers a well designed catamaran to have two to three times less roll amplitude than an equivalent monohull with equal accelerations. Experience with monitoring of WPC has indicated that the accelerations and motions in beam seas are more than acceptable and are well within HSC code limits. Exploring the concept of high GM, catamarans by their nature have much higher GM values; hence their stability is correspondingly higher. The natural period of a monohull is generally calculated with reasonable accuracy by the following formula; T= 2 it would seem to indicate hence higher accelerations. does not account for is that increases. The formula does 1.25I xx ∆g GM F ∆ g GMF = mass of ship = gravity = fluid metacentric height Ixx = roll moment of Inertia (GM accounting for free surface effects) a shorter roll period and What the monohull theory the added roll inertia also not account for damping forces which increase with hull separation. Dubrosvsky, (2001) states that the wider the overall beam of a multihull the smaller the motions and that a catamaran does not roll like a monohull but that each hull heaves up and down. For catamarans he xx considers the added roll inertia to be equivalent to the heave value as opposed F to the roll value usually used for a monohull. For mono-hulls in heave the added inertia is generally equivalent to the ∆ whereas = mass ship actual inertia, for rollof is 25%. T= 2 1.25I ∆g GM g = gravity This formulaGM shows that the metacentric natural roll period increases = fluid height F with increasing overall beam which would provide a (GM accounting for free surface effects) subsequent decrease in acceleration levels. Accelerations Ixx = roll moment of Inertia are proportional to the inverse of the period squared, Martin, (1994). T= 2 Boa g Fancescutto, (2000) tested models in beam seas and found that an increase in hull separation decreased motions. He found that only at small values of hull separation did the response exhibit peak like behaviour similar to a monohull. Wahab, (1971) tested models and found that roll response decreased with increasing hull separation. He also found that roll response was lower at forward speed than at zero speed. Davis (2006) has found a decrease in roll motion with increasing hull separation, figure 3 shows the peak like behaviour disappearing at higher separation. 3 The 1.25 factor represents an approximation of the added roll inertia, Lloyd (1998). Added roll inertia is assumed to be 25% of actual inertia for a monohull vessel. Lloyd (1998) recommends a natural roll period of between 10 to 20 seconds to ensure acceptable roll motions. To increase the roll period to within these recommended values fluid metacentric height (GMF) can be reduced or roll moment of inertia (Ixx) increased. Reducing GMF is possible in a monohull by raising the vertical centre of gravity. This is at the expense of stability though so is not always possible. It is more difficult in smaller vessels as these vessels usually have high GM for their length, Martin, (1994). T= 2 Boa g Catamarans do have high centre of gravity but due to their hull separation also have high GM which is a function of transverse second moment of waterplane area, so increasing hull separation will generally increase this value. The benefit of this is increased stability. If the monohull theory is followed 16 Incat THE Magazine Issue 34 S/L=0.2 2.5 S/L=0.24 2 S/L=0.28 S/L=0.4 1.5 S/L=0.5 1 0.5 0 0 2 4 6 8 10 Dimesionless encounter frequency Figure 3, ROLL RAO IN BEAM SEAS AT 40kt: NPLHULL FORM CATAMARAN (2500 tonnes, 102m length) (Computed by BEAMSEA including sway motion), S = hull spacing, l = waterline leng English Channel Studies were undertaken during the design of the Incat 112 metre where the overall beam or hull separation was decreased by 4 metres, increased by 4 metres and 8 metres compared to the original. The original was equivalent to the hull separation on the 98 metre vessel. Referring to figures 4 & 5 some of the results of this study can be seen where the motions and accelerations reduce significantly with wider hull separation and increase significantly with decreased separation. From the original hull separation, (same as 98 metre) to the plus 4 metre separation, (today’s 112 metre measurement) the accelerations reduced 25%, DNV, (2000). In figure 4 it can be seen the period at which the peak response occurs has also shifted, a higher period for the increased hull separation. Dubrovsky (2001) has also found that increasing hull beam to draft ratio reduces roll motions. On the 112 metre the hull beam to draft ratio has increased approximately 15%. The side effect of this is a reduction in resistance. Active ride control and viscous damping, Faltinsen, (1993), is neglected in figures 4 & 5, the effect being that motions would be expected to be even less in reality at speed. 12 beam -4 m 20.00 orig beam -4 m 15.00 beam +4 m orig beam +4 m 10.00 COG 5.00 beam +8 m beam +8m MPD 0.00 0 1 2 3 4 5 Hull Separation Figure 5, comparative accelerations at varying hull separation, no ride control, COG is Centre of Gravity, and MPD is Main Passenger Deck.

Tab RCS, Motion Sickness Incidence (MSI) along Port side, 2 hour exposure. In monohull theory, it is always thought that a higher natural roll period gives the lower motions. When looking at figure 2, which plots the wave slope versus wave length, it can be seen why this may be the case the shorter the wave period the steeper the face of the wave. Generally it is assumed that the vessel will roll no more than the angle of the wave, Lloyd (1998), so the higher the natural period the longer the wave that the vessel reacts to, so the lower the roll angle. NATURAL ROLL PERIOD MDI (Maritime Dynamics Inc.) (2001) found significant reductions in motions and accelerations in beam seas for the 112 metre over the 98 metre. This would seem to be from the increased hull separation and the greater effectiveness of the ride control. The trim tab has a greater aspect ratio on the 112 metre due to the wider hulls and also greater lever arm due to increased hull separation. Greater aspect ratio equals greater lift. The MDI results vary depending on wave height and period but reductions in roll angle and Motion Sickness Incidence (MSI) are generally in the region 25% to 35% but can be up to 50% depending on wave period and height. Refer to figures 6, & 7, tab 1 for the 112 metre refers to a tab similar to the 98 metre in aspect ratio. Tab 2 refers to a higher aspect ratio tab as fitted to the 112 metre in the final design. 25.00 The other advantage is that longer waves are statistically less likely to occur hence the resonance will occur less frequently. So for catamarans and other multi-hulls it would be important to increase the natural period in roll, this can be done by increasing the hull separation, Dubrovsky, (2001), Francescutto, (2000).

Incat THE Magazine Issue 34 17 PITCHING/SLAMMING TUNNEL HEIGHT Tunnel height or clearance is thought to be the most important factor to reduce slamming that arises from pitching motions; other factors are longitudinal stability, ship length vs. wave length, block and prismatic coefficients and foils. An increase in tunnel height twofold can reduce accelerations by 4-5 times, Dubrovsky (2001). Outline of the corresponding bow section on 112m Wave Piercing Catamaran Davis, (2006) created drop test experiments with varying shapes of centre bow and found that the shape of the centre bow is critical to impact pressures. A shape more similar to the 112m shape reduced impact pressures by 50% compared to the 96m shape. This is expected to translate into significant reductions in accelerations during slamming events. flare angle results in a further 21% reduction in the fore body side Impact loads Although it is desirable to increase the tunnel clearance to reduce slamming loads, practically it may not be so, e.g., raising the tunnel clearance means increasing the freeboard making it much more difficult (cost and weight) to construct ramps down to low wharves or pontoons. Safety in following seas may be compromised if the tunnel clearance is excessive. The increase in tunnel clearance may also unnecessarily increase structural weight. A compromise reached with the 112 metre design was to increase the tunnel height forward only; the shoulder area of the centre bow being lifted significantly, as shown in Figures 8 & 9, while the centre-line area was left relatively close to the water to ensure early immersion and subsequent damping and motion control. Part of the flat cross structure aft of the centre bow was also raised in the process. Shaping of the centre bow shoulder Increasing the bow clearance results in a 24% reduction in the bow impact load Improving the bow HSV-X1 Joint Venture FIGURE 8. Comparison of tunnel clearance between 96m and 112m vessels, HSV-X1 is a 96m vessel. area was also done to eliminate flat surfaces, which can produce very high accelerations and pressures. The 96 metre series of vessels have very low tunnel clearance and very flat surfaces. The 98 metre being the ‘Evolution’ has been totally re-shaped in that area to reduce flat surfaces and increase tunnel clearance in the shoulder area. Compared to the 98 metre, MDI (2001) found that in head or bow quartering seas MSI for the 112 metre reduced between 10 and 20% depending on the wave period and sea state. Refer to figures 6 & 7. LENGTH It can be seen that length (size) has a significant effect on motions especially in the smaller to medium size range between 500 and 2000 tonnes, refer to figure 10. This is similar to what Lloyd (1998) found where accelerations reduce rapidly with length increase in the smaller vessels and reduce less rapidly at greater lengths. For example from LWL 86 metre to 115 metre, rms accelerations 18 Incat THE Magazine Issue 34 reduced 40%, whereas from LWL 250 metre to 300 metre, rms acceleration only reduces 10% Lloyd, (1998). The 86 metre LWL is significant in that it represents a 96 metre WPC and the 115 metre LWL represents a larger competitor. VESSEL C.L. Most discussion suggests that a longer vessel will reduce motions. A vessel of infinite length will never respond to a wave, every wave will be shorter than it is and a wave of infinite length would have infinitely small or zero steepness. But an infinitely small length ship will respond to every wave it meets as every wave is longer that itself. A very small length wave is very steep so the infinitely small ship will simply follow the very steep wave profile with worst case motions. As the vessel and equivalent wave length is increased the wave steepness is reducing. It can be seen from figure 2 the wave steepness reduces more rapidly for the shorter lengths hence the high reduction in motions for vessels in that length. Steep long waves are less likely to occur statistically and practically at a certain steepness the wave will break limiting its maximum steepness. 1900t @ 3116 W.L FOR #112m 1427t @ 3416 W.L FOR #061 FIGURE 9. Comparison of tunnel clearance between 98m and 112m vessels RIDE CONTROL Sclavounos, (2003) has found that ride control can be very effective in eliminating resonant peaks in heave and reducing resonant peaks significantly in pitch. Higher speed and higher aspect ratio of ride control surfaces increase the effectiveness of ride control significantly. The 112 metre simulations from MDI (2001) predict improvements with the higher aspect ratio trim tabs fitted due to the wider hull beam and improvements from the new higher aspect T-foil similarly. CONCLUSIONS Vessel is operating at or near its resonance period. When at resonance the waves do not need a lot of energy to create vessel motion so the ride control is most effective as less energy is required to control that motion. Dubrovsky (2001) found that pitching motions can reduce significantly with a bow foil with accelerations reduced by up to 30% with the correct location and area of foils. Sea keeping is heavily dependant on the size of the vessel; length, beam and weight are crucial parameters. A wider, longer vessel will generally have improved sea-keeping compared to the shorter, narrower vessel. The improvement in seakeeping given the right sea state could be significant, in fact in the right conditions motions could reduce to insignificance if the vessel operates in wave periods outside of its own natural periods. Ride control is very effective in reducing the peak motions especially in resonant conditions. Motions can be reduced generally by 20% with active ride control but up to 50% depending 60 500 tonnes (%) on sea state. 1000 tonnes 50 2000 tonnes 40 5000 tonnes The 112 metre WPC when compared to 30 10000 tonnes the 96 metre and 98 metre WPC can offer 20000 tonnes 20 improvements of at least 25% but up to 50% 10 depending on sea state. 0 0 5 10 15 20 25 The wider hull separation, although increasing GM (and stability), does not Vessel speed (m/s) lead to an increase in motions but in fact (a) Monohull vessels reduces motions and quite significantly in 1000 tonnes 60 2000 tonnes 50 The WPC platform allows for optimisation 5000 tonnes of the demi-hull shape for maximum 10000 tonnes 40 (%) the right conditions. 500 tonnes 70 efficiency.

Today the company is mainly run by two sons Harald and Bernd, but Gerhard is still active in his hobby: to design and develop advanced couplings and shafts. 20 In certain market niches, CENTA is the market leader - e.g. couplings for small boats and carbon fibre shafts. In other areas CENTA is number two - e.g. flexible couplings for ship Today, CENTA is a world leading, medium sized manufacturer of flexible propulsion (torques up to 650kNm), couplings for diesel driven couplings and shafts for the marine and a range of other industries. construction equipment, and couplings for wind turbines. Incat THE Magazine Issue 34 CENTA works in close cooperation with all ship classification societies and holds several quality system certificates in addition to around 60 type approvals for ship propulsion and auxiliary couplings. Several dynamic test benches (torques up to 750kNm) allow CENTA to measure all relevant data for couplings, such as dynamic torsional stiffness, damping factor, allowable energy loss, reacting forces under misalignment etc. Furthermore, all kinds of fatigue tests can be run and reliable data for the rating of the couplings can be established under normal and high ambient operating temperatures. Speeds up to 10,000 rpm can be run with small couplings to test their resistance to centrifugal forces at high rotational speeds. In other words, CENTA is fully equipped with several different test benches to allow new designs or applications to be rapidly assessed. CENTA’s workshop at the headquarters in Haan (near Dusseldorf/Cologne) is fully equipped with modern CNC machine tools for turning, milling, broaching and balancing. In addition, CENTA Transmissions Ltd in the UK also has a modern production facility, while CENTA Corporation in the USA and CENTA MP in Shanghai have commenced their own machining operations. Layout of carbon fibre shaft for Incat hull 064 CARBON FIBRE SHAFTS CENTA Headquarters CENTA’s Carbon Fibre Shaft History In 1996 CENTA began to build up expertise in carbon fibre shaft technology. In close cooperation with the Technical University of Darmstadt and various classification societies, the basics in theory and practical testing were established. Numerous bench tests confirmed the theoretical calculations. Shafts of 6m length and torques up to 200kNm were tested and the limits evaluated. In the beginning each shaft had to be tested at full scale at 1.3 times rated torque. There is now so much confidence in the calculations that (normally) practical tests are not required. The shafts are specified with safety factors of five to six times rated torque. CENTA has delivered more than 600 Carbon Fibre shafts for ship propulsion in the last 10 years which are all performing reliably. The largest shaft is transmitting 23MW from a gas turbine to the waterjet of a luxury yacht. Incat THE Magazine Issue 34 21 Finite Element Analysis How is a Carbon Fibre Shaft specified? We know from the technical data the required torque and shaft speed for the transmission. Based on our knowledge, we pre-select a tube with a certain inner diameter. This diameter is – wherever possible – based on an existing mandrel. Then we calculate the wall thickness, the number of layers, the grade of fibre and the orientation (angle) of the fibres. The torque capacity and the torsional and lateral stiffness can be influenced by the winding angle. For example, winding angles of 45 degree provide the highest torque rating. Small winding angles, of about 10 degree, almost parallel to the axis of the tube, provide lower torque, but higher lateral stiffness, and hence higher critical speed and respectively longer spans without intermediate bearings. In practice we build up the tube mostly with a combination of different winding angles in order to get the highest rating for the given conditions, with the lowest content of the expensive fibres. The connection between the Carbon Fibre tubes and the steel fittings is one of the key points. At first we glue the parts together in order to fix them to one another. Then we drill and ream one or two rows of precise tapered bores. Tapered pins of high grade steel are then pressed in and secured by glue and inner nuts, and bonded Carbon Fibre ribbon over the pins on the outside of the tube. This design is proprietary and patented to CENTA. The transmission of the torque between the tube and the metal fitting is safely provided by the pins alone, the glue just gives an additional safety margin, but the connection does not rely on it. 22 Incat THE Magazine Issue 34 System Engineering and a pin and bush coupling that adjusts axially and that has in many The earlier that CENTA is included in a project, the better recommendations bush couplings are maintenance free.

With Carbon Fibre shafts typically about 70% of the weight can be saved compared to solid steel shafts. In addition, carbon fibre shafts can span much longer distances, hence many bearings and their foundations can be saved. Fewer bearings means further weight savings, plus: less cost, less assembly work, less noise, less maintenance and less energy loss. Incat and CENTA CENTA has been in the Carbon Fibre business for more than a decade, with the highest market share for fast ferries. We have of course always viewed Incat as a very interesting potential customer, and were very pleased to provide shafts for hulls 064 and 065. Carbon Fibre production cell Such dangerous reacting forces can result from misalignments, assembly errors, thermal expansion, flexing of the hull, of bearing or engine foundation, flexible mounts and so on. Practice has proven this philosophy! Therefore CENTA has developed several kinds of flexible couplings that provide substantial axial and angular flexibility with very low (hence much safer) reacting forces. The most forgiving coupling is the unique, patented CENTALINK, with links. Integrated into the links are pre-compressed, bonded rubber bushes and A recent visit to CENTA by Incat Chairman Robert Clifford provided us with the opportunity to not only discuss the 112m Japanese project but also to become more familiar with each other.

This wonderful group of islands is divided into Gimnesias (Mallorca, Menorca and Cabrera) in the North, and Pitiusas (Ibiza and Formentera) in the South-West. Each of the islands has a strong personality all of its own, and has much to offer. Sparkling sea, sandy beaches, endless sunshine and lively nightlife are just the start. Look beyond this and a treasure trove of atmospheric fishing villages, fragrant orange orchards, magnificent bush walks and prehistoric sites is revealed. The cuisine of the Balearic Islands is of Mediterranean tradition and has gained a great reputation throughout Spain. It is extremely varied - more than 600 different recipes are considered typically “Balearic”. The internationally best known recipe is mayonnaise - although there are few who know it originally came from Menorca. In Spanish language it is called Salsa Mahónesa. Wine is produced only in Mallorca, as well as several liqueurs. A speciality of Ibiza is its herb-flavored liqueur - not a bad way to finish an opulent meal.

Medieval Towns and Romantic Fishing Ports The island of Mallorca is probably the most popular of the Balearic Islands, attracting many visitors since the 1950s. Tourism at Mallorca started to develop in the 1920s - until the Spanish Civil War it was mainly intellectuals and artists who were attracted by this island. The capital, Palma de Mallorca is home to more than 300,000 people and boasts an attractive old quarter, Gothic churches and stylish bars. The city and its beautiful bay, Bahía de Palma is ideal for an excursion by bicycle where you will see many outstanding beaches. The north and east of the island are the least developed. The northwest coast is spectacularly beautiful - dominated by the Serra de Tramuntana Mountains and boasting cool pine forests, charming villages and attractive olive groves. The region is also ideal for trekking.

Wild rosemary grows in abundance and the island boasts idyllic sandy beaches and fine walking and cycling trails. The sea is visible from practically any point of the island, and there are numerous great beaches and lonely bays, some of them with incredible grottos. located in the midst of large pine woods which end at the beach of Es Pujols in the North and at the beach of Mitjorn in the South. The road to La Mola, located at the very South-East of the island, leads 193 metres above sea level. From the view-point El Mirador you can enjoy an outstanding panorama. Formentera’s western part offers untouched nature. Perhaps the most beautiful beach is Cala Saona. With springtime temperatures most of the year, its rich vegetation of pines as well as palms, and quiet and relaxed ambience, Formentera is a true paradise. Nature Reserve When visiting Cabrera, which is located close to the Mallorcas southern coast, and its lonely beaches, you will really feel like Robinson Crusoe. Cabrera was declared a nature reserve in 1991 and since then access is controlled by the Spanish National Institute for the Conservation of Nature. Permission is required to visit the island and access to some areas is forbidden. Most beautiful is certainly Cabrera’s lonely coast where dolphins at play can be observed. In the bay of Cala Gandulf is a beautiful cave, Cova Blava. In its interior you will experience unique reflections of light. Apart from the beauties of nature, the pirate fortress of the 14th Century is certainly worth a visit. So whether it’s the legendary nightlife in Ibiza, the cool forests of Majorca, the fine beaches of Formentera or the prehistoric sites in Menorca, the Balearic Islands offer a range of unforgettable experiences. 26 Incat THE Magazine Issue 34 Ferry operator Baléaria acts as a bridge between the Baléaric Islands and also the mainland Spain.

Incat THE Magazine Issue 34 Proven Technology Together with Incat and Bollinger, Revolution Design has offered as the SeaFrame base for JHSV, the Revolution 112 metre design which has recently been delivered in civilian guise to HigashiNihon Ferry in Japan, the first of two such vessels for operation between Aomori and Hakodate. This vessel, Natchan Rera, the first of a number of 112 metre vessels on order or in negotiation with Incat, has revolutionised Tsugaru Strait crossings for its Japanese operator and has attracted major interest from world wide operators. This vessel design, having already been built and proven in service, provides the US Navy with a unique opportunity to observe the offered vessel in commercial operation. It is expected that few other designs offered to the Navy will have actually been built and successfully and economically operated. By the time a Phase 2 award is made both of the HigashiNihon vessels will be have been in operation for some time and two other 112m vessels will be in production at Incat. These vessels will have accumulated many thousands of operating hours, which no other design can claim. Initially, both the Department of the Army and the Department of the Navy pursued separate programs to meet their requirements for intra-theater connectors. However, a decision was made to combine efforts, as collaboration between the Army and Navy would offer increased cost savings for both armed services. The JHSV program combines the Army’s Theater Support Vessel (TSV) program with the Navy and Marine Corps High Speed Connector (HSC). Three prototype High Speed Vessels, HSV-X1 Joint Venture, TSV-1X Spearhead and HSV 2 Swift, have already been used to support operations in the Global War on Terrorism and during Operation Iraqi Freedom. They have been deployed to the Horn of Africa, Persian Gulf and Southeast Asia. Swift has supported relief operations in Indonesia and in the Gulf Coast region following hurricane Katrina. In both cases, Swift’s high speed and shallow draught combined to make it an ideal platform for the delivery of relief supplies and support of other platforms operating in the area. During operations following Katrina, Swift was able to access ports inaccessible to other ships in the logistics force, and therefore played a critical role in the early delivery of supplies. The 112m design takes lessons learnt from the U.S. experience and incorporates these to create a vessel with even greater ability than the previously charted vessels. Incat THE Magazine Issue 34 29 joint high speed vessel JHS V update Proven Technology HSV -2 Swift HSV-XI Joint Venture JHSV Specification The ship will be designed for a maximum crew accommodation of 41 persons berthed in staterooms, have permanent berths for 104 embarked troops, and have 312 airline style seats for embarked forces. A dedicated interior Roll-on/Roll-off mission deck size of no less than 1,858.06 m2 is required. The ship must be fully supportable within the current commercial and DoD supply chains. She will be capable of transporting 544.31 metric tonnes (MT) (threshold); 635.03 MT (objective) of personnel, supplies, and equipment 1200 nautical miles (NM) at an average speed of 35 knots in a significant wave height of 1.25 m (threshold/objective) without refuelling. The minimum transit range (without payload) TSV-IX Spearhead is 4700 NM (threshold); 5200 NM (objective) at an average transit speed of 25 knots in a significant wave height of 1.25 m (threshold/objective) without refuelling. The JHSV will be capable of transporting personnel, equipment and supplies over operational distances in support of manoeuvre and sustainment operations. She will transport Army and Marine Corps company-sized units with their vehicles, or reconfigure to become a troop transport for an infantry battalion. A flight deck for helicopter operations is included as is a loading ramp for fast and efficient vehicle discharge. The ramp will be suitable for the types of austere piers and quay walls common in developing countries. The JHSV will also be shallow draught, 4.5 metre (under 15 feet) which will further enhance access by enabling the JHSV to operate in shallow waters. This makes the JHSV an extremely flexible asset able to support a wide range of operations including manoeuvre and sustainment, relief operations in small or damaged ports, flexible logistics support, or as the key enabler for rapid transport. 30 Incat THE Magazine Issue 34 Local Knowledge…global service - Tasmania’s Leading Freight Brokerage – Providing Incat with Global Logistics solutions for over 5 years, including: U International Air and Sea Freight Import/Export - over 500 Offices World Wide U International Courier/Door to Door Service U International Perishable Logistics U Domestic Freight Service within Australia U International Bulk Mail Service U Dangerous Goods Packing and Handling U Specialised Art Work and Wine Packaging and Freighting Now Offering: U Warehousing, Logistics and Distribution U On Site Container Hire and /or Storage U Freight and Logistics Consultancy Service U On Site Staging, Workspace and Office Facilities for Special Projects Check out our Front Counter Rates for your National and International courier needs! www.totalfreightsolutions.com.au Unit 2, 12 Maxwell’s Road, Cambridge Phone: 03 6248 4012 Mobile: 0418 580 544 E: [email protected] Incat THE Magazine Issue 34 31 &/(*/&&3*/("6453"-*" Custom made solutions from the primary stage of design to site installation.

Justin Merrigan Following fast on the heels of the earlier Cat-Link IV was a sister ship for the Scandlines Cat-Link A/S service between Århus and Kalundborg., Cat-Link V. On her delivery voyage from Tasmania to Europe in July 1998 Cat-Link V became Incat’s third Blue Riband craft, achieving the fastest Atlantic 049 a ditched light aircraft mid Atlantic a record of 2 days, 20 hours and 9 minutes was still achieved at an average speed of 41.205 knots, a record which remains unbeaten almost ten years on. In fact she broke two world records on the passage, also becoming the first ship to travel 1018.5 nautical miles in 24 hours with an average speed of 41.284 knots.

Before entering service with Master Ferries the Coming off charter to Mols-Linien in July 2005 put the craft in a very newly named Master Cat underwent a major refurbishment, not least of all the fortunate position, there being no other equally capable ship available in installation of a large new duty free shop in the aft cabin, allowing passengers to the market for immediate delivery. The ferry was therefore in demand, take full advantage of Duty Free opportunities between the two countries. with no less that half a dozen operators inspecting her for service in 2006. At the end of 2007, MasterFerries merged with Norwegian operator Fjord Line, New European operator Master Ferries purchased the craft in March 2006 the MasterCat’s operations being marketed under the latter’s well known brand for entry into service on their new route between Kristiansand in Norway from 2008.
